Lets say I have the following:
A = [a1,a2,a3,a11,a22,a33]
When I say
Index = strfind(A,'a1')
Matlab tells me that there are 2 a1 because it considers the a11 as well. Same for a2 or a3.
How can I specify that I want a1 only.
I appriciate the help.

Surafel - use strcmp instead
>> A = {'a1','a2','a3','a11','a22','a33'};
>> result = strcmp(A,'a1')
result =
1 0 0 0 0 0
